Utility Assistance Program

The Wisconsin Department of Administration (DOA), Division of Energy Housing and Community Resources (DEHCR), is introducing the Low Income Household Water Assistance Program (LIHWAP).  LIHWAP is designed to provide direct financial assistance to reduce arrearages charged to eligible drinking water and wastewater utility customers.

Households eligible for LIHWAP will be required to first complete a Wisconsin Home Energy Assistance Program (WHEAP) application.  The federal Health and Human Services agency recently approved Wisconsin’s implementation plan.  Energy Services Inc. (ESI) is the agency responsible for administration of LIHWAP benefits in the State of Wisconsin, and the agency expects disbursements for water bill assistance to begin in September 2021.  ESI will disburse an amount on a one-time basis to the utility, which will be responsible for applying the assistance to an eligible customer’s bill.

Customers interested in applying for LIHWAP or seeking more information should contact

Energy Services at 1-800-506-5596. 

Customers may also go online to complete a WHEAP application at https://energybenefit.wi.gov/

Flushing Guidance

Fond du Lac Water Utility is advising businesses and other water customers about the importance of following procedures when reopening a location where water has been stagnant in pipes.

Plumbing systems that were inactive for an extended period, such as during the shutdown for the Coronavirus (COVID-19) pandemic, can pose a health risk. Water that has not been circulated can create a potential for pathogen growth because the disinfectant in the water will dissipates over time. This stagnant water can allow disease causing pathogens to grow within the water pipes.

As some businesses start re-opening, it is recommended to follow the listed steps to maintain water quality. The purpose of building flushing is to replace ALL water inside building piping with fresh water, not just drinking water.

  • Flush hot and cold water through all points of use (e.g. showers, sink faucets, appliances, icemakers, hot water heaters, drinking fountains, etc.)
    • Flush cold water lines before hot water lines.
    • Flushing may need to occur in segments, depending on size of individual rooms or if a building contains multiple floors.
    • Flushing should start at the lowest level, the one nearest to the building’s water supply.
    • Replace all point-of-use filters, including filters in refrigerators.
